MDC Linear Progress ships with an MDCLinearProgressFoundation class that external frameworks and libraries can
use to integrate the component. As with all foundation classes, an adapter object must be provided.
The adapter for linear progress must provide the following functions, with correct signatures:

| Method Signature | Description |
| --- | --- |
| addClass(className: string) => void | Adds a class to the root element. |
| removeClass(className: string) => void | Removes a class from the root element. |
| hasClass(className: string) => boolean | Returns boolean indicating whether the root element has a given class. |
| forceLayout() => void | Force-trigger a layout on the root element. This is needed to restart animations correctly. |
| getPrimaryBar() => Element | Returns the primary bar element. |
| getBuffer() => Element | Returns the buffer element. |
| setStyle(el: Element, styleProperty: string, value: string) => void | Sets the inline style on the given element. |

MDC Linear Progress Foundation exposes the following methods:

| Method Signature | Description |
| --- | --- |
| setDeterminate(value: boolean) => void | Toggles the component between the determinate and indeterminate state. |
| setProgress(value: number) => void | Sets the progress bar to this value. Value should be between [0, 1]. |
| setBuffer(value: number) => void | Sets the buffer bar to this value. Value should be between [0, 1]. |
| setReverse(value: boolean) => void | Reverses the direction of the linear progress indicator. |
| open() => void | Puts the component in the open state. |
| close() => void | Puts the component in the closed state. |
